Abstract:
None-invasive geophysical methods are nowadays commonly used in archaeological studies. In this study, an integrated geophysical investigation utilizing both the electrical resistivity tomography and magnetic techniques was performed at one of the unexplored sites of Sungai Batu archaeological complex, Kedah, Malaysia. The main purposes of this survey were locating buried archaeological artifacts and determining the shallow subsurface geology. The geophysical study proceeded in two steps. First, the magnetometry survey was performed employing a G-856 proton precession magnetometer over 13 lines. Then, the Electrical Resistivity Tomography (ERT) survey was designed in 5 lines utilizing a pole-dipole array. The ERT data was processed by using the smoothness constrained least-squares inversion. The magnetometry results displayed two main anomalies which had a high magnetic value, indicating buried structures. The ERT results demonstrated three main layers of alluvium soil mixed with sand and clay, saturated zone and the bedrock layer. The correlation of two methods indicated a good agreement between magnetic and resistivity results. An excavation test, conducted by archaeologists, confirmed the geophysical results. Consequently, the survey results revealed that integrated geophysical techniques are useful tools to obtain more detailed information about underground for designing a fast and cost-effective archaeological excavation.
